To @ZZ whom uma/y concern:

Be it known that I, HINRICH LBBEN,

l farmer, a Subject of the Grand Duke of oidenburg, a\nd a resident ofl-Iartwarderwurp, in the Grand Duchy of Oldenburg, Germany, haveinvented certain new and useful Gymnastic Apparatus for ExecutingArm-Circles,

' of which the following isa full and clear specification. i

The invention has been patented in France August 10, 1897, No. 269,511.

My "invention consists of an apparatus for gymnastic purposes, andespecially for executing with the arms a motion where the stretched.arms describe a circle. This motionf'. is ordinarily difiicult'toperform, While with the apparatus hereinafter described it will beexecuted in an easy and regular-manner.

My invention consists, essentially, of two handles attached to cranks bymeans of universal or ball-and-socket joints. It is constructed asfollows, reference being had to the accompanying drawings, in which.-

Figure 1 is a front view, and Fig. 2 a plan, of the apparatus whenplaced in the corner of a room. Fig. 3 is a View of the apparatuslattached to two standards.- Figs. 4 to 7 are details of the apparatus.Fig. 8 is a modification of the apparatus.

The handles dare connected with the cranks b by means of universal orball-and-socket joints. The pivot is supported by a piece CZ, providedwith three arms, these arms being guided in slots c, iitted in the wall,Figs. 1 and 2, or in the standard, Fig. 3, for the purpose of moving thecranks vertically, according to the size of the person using theAapparatus. The length of the cranks can also be varied by iixing thepivot in one of the holes :fitted in the crank, as shown in Figs. 4 and5. In Fig. 7 the crank is connected to the pivot o by means of ahinge-joint, whereby the angle between the crank and the wall may bevaried and the crank iiXed at any desired angle to the wall.

A very simple modication of the apparatus is shown in Fig. 8. Thebearing d of the pivot is fixed directly to the wall by means of awall-'plate d2, which is provided with several holes for the screws,thereby permitting an adjusting of the apparatus in vertical sense. Thecrank b and the end plate dof the pivot are also provided with severalholes in order topermit a varying of the length of the crank.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In an exercising-machine for executing arm movements, the combinationof a sup-A port, a crank pivoted thereto to assume various angles inrelation to the pivot and free to move by the power of the personexercis ing applied to said crank at its outer end and Va handle havingapivotal connection with the outer end of the said crank allowing saidhanv dle movement in a plurality of directions, substantially asdescribed. f

2. In combination in an exercising-machine for executing arm movements,a pair of pivoted cranks arranged to move in planes diverging fromV eachother and handles pivotally attached to said cranks, substantially asdescribed.

' 3. An exercising-machine comprisinga support, a crank pivoted theretoin oblique relation to the wall to which the support is attached, and ahandle having pivotal connection with the outer end of the said crank,substantially as described.

4:. A gymnastic apparatus comprising a slotted support` and a crankhaving a handle with a connection between the arm of said crank and saidsupport to permit pivotal movement of the crank-arm, the said slottedsupport allowing a vertical adjustment of the parts to suit persons ofdifferent heights and without changing the sweep of the cranks.

Signed at Brake, Grand Duchy of Olden burg, this 7th day of January,1833.
